Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and more specifically, to a bearing housing for rolling mills that is easy to maintain. Background Technology

[0002] A rolling mill is a piece of equipment that enables the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. A typical rolling mill mainly consists of rollers, a frame, a roller gap adjustment device, a roller temperature adjustment device, a transmission device, a lubrication system, a control system, and a roller removal device. In order to ensure that the rollers can rotate in the correct position and thus ensure the smooth progress of the rolling process, bearing seats and bearings are generally installed on the outside of the mill to provide stable support for the rollers.

[0003] A search revealed a prior art disclosure of a rolling mill bearing housing that is easy to maintain, with publication number CN217570189U. The specification states: "By setting abutment plates on both sides of the upper end of the rolling mill body, a rotating rod drives the main gear to rotate. The main gear rotates on a fixed plate via a rotating base. The rotation of the main gear drives two auxiliary gears to rotate, and the auxiliary gears drive a double-shaft lead screw to rotate. Simultaneously, the double-shaft lead screw can drive two abutment plates to move towards each other via side plate one and side plate two, thereby achieving the effect of clamping and fixing the bearing housing. The main gear and auxiliary gears facilitate the installation and disassembly of the bearing housing."

[0004] However, in actual use, the way the plate is moved by the dual-axis lead screw, gear and other structures requires the worker to rotate the lever many times. Especially when the bearing housing needs to be frequently installed and disassembled, it will greatly affect the production efficiency. Moreover, the dual-axis lead screw, gear and other structures are installed on the outside of the bearing housing, which makes the space occupied. In some small or compact rolling mills, the addition of such external structures will make the overall layout of the equipment complicated. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a bearing housing for rolling mills that is easy to maintain. This solves the problem that the existing method of adding a clamping assembly composed of a double-screw or other structure to the outside of the bearing housing not only makes the overall layout of the equipment complicated when used in some small or compact rolling mills, but also greatly affects production efficiency when the bearing housing is frequently installed and disassembled.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bearing housing for rolling mills that is easy to maintain, comprising a bearing housing body, a mounting ring slidably connected to the front side of the bearing housing body, a plurality of connecting blocks 1 fixedly connected to the rear end of the mounting ring 1, a mounting ring 2 slidably connected to the inner side of the mounting ring 1, a plurality of connecting blocks 2 fixedly connected to the rear end of the mounting ring 2, a plurality of connecting grooves being formed inside the front side of the bearing housing body, a connecting block 1 slidably connected to the inside of a connecting block 2, and a connecting block 2 slidably connected to the inside of a connecting groove, a slot being formed on one side of the inner wall of the connecting groove, a locking block being engaged inside the slot, and the locking block penetrating through the connecting block 1 and the connecting block 2.

[0007] The inner wall of the connecting groove has an installation groove on the other side. The side of the card block away from the card groove is fixedly connected to an installation piece. The other end of the installation piece is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope.

[0008] The bearing housing body has a snap-fit ​​groove on both the upper and lower sides. The inner walls of the two snap-fit ​​grooves are provided with slots on the adjacent sides. A limit rod is fixedly connected inside the slot. A pull block is fixedly connected to the end of the pull rope away from the mounting plate. Two insert rods are fixedly connected to the adjacent sides of the two pull blocks. A rubber block is fixedly connected to the outside of the insert rods.

[0009] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0010] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0011] The pull block is slidably connected inside the snap-fit ​​groove, and the limiting rod is slidably connected inside the pull block through the insert rod.

[0012] The insertion rod is slidably connected inside the slot, and the outer surface of the rubber block is an arc block structure that engages with the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by installing a locking block inside the bearing housing body and using the locking block to engage the mounting ring with the bearing housing body, the space occupancy rate is greatly reduced, allowing the structure to be applied to various rolling mills, resulting in high flexibility of use. Furthermore, the bearing and bearing housing can be disassembled by moving the locking block, thus facilitating the maintenance of the bearing housing, resulting in high maintenance efficiency and high economic efficiency.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a bearing housing for rolling mills that is easy to maintain, including a bearing housing body 1. A mounting ring 1 2 is slidably connected to the front side of the bearing housing body 1. Multiple connecting blocks 1 3 are fixedly connected to the rear end of the mounting ring 1 2. A mounting ring 2 4 is slidably connected to the inner side of the mounting ring 1 2. The mounting ring 1 2 and the mounting ring 2 4 work together to confine the bearing inside the bearing housing body 1. Multiple connecting blocks 2 5 are fixedly connected to the rear end of the mounting ring 2 4. Multiple connecting grooves 6 are opened inside the front side of the bearing housing body 1. The connecting block 1 3 is slidably connected to the inside of the connecting block 2 5, and the connecting block 2 5 is slidably connected to the inside of the connecting grooves 6, so that the connecting block 2 5 can be embedded inside the connecting block 1 3 and are jointly limited by the connecting grooves 6. A slot 7 is opened on one side of the inner wall of the connecting groove 6. A slot block 8 is engaged inside the slot 7, and the slot block 8 passes through the connecting block 1 3 and the connecting block 2 5, so that the slot block 8 can limit the connection block 1 3 and the connecting block 2 5, thereby connecting the mounting ring 1 2 and the mounting ring 2 4.

[0025] When it is necessary to disassemble the bearing housing body 1 from the bearing, by moving the locking block 8, the locking block 8 can be disengaged from the slot 7 and the interior of the connecting block 3 and the connecting block 5. Then, by pulling the mounting ring 2 and the mounting ring 4 forward, the mounting ring 2 can drive the connecting block 3 to disengage from the interior of the connecting slot 6, and the mounting ring 4 can drive the connecting block 5 to disengage from the interior of the connecting slot 6. Thus, the bearing is no longer restricted, and the bearing can be removed. This eliminates the presence of other structures inside the bearing housing body 1, making it easier to maintain the bearing housing body 1.

[0026] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 8, an installation groove 9 is provided on the other side of the inner wall of the connecting groove 6. The locking block 8 is slidably connected inside the installation groove 9. The installation groove 9 provides moving space for the locking block 8. An installation piece 10 is fixedly connected to the side of the locking block 8 away from the locking groove 7. The installation piece 10 is used to pull the locking block 8 to move. The installation piece 10 is slidably connected inside the installation groove 9. The installation groove 9 limits the installation piece 10 so that the installation piece 10 will not deviate when sliding. A pull rope 11 is fixedly connected to the other end of the installation piece 10. The pull rope 11 is used to pull the installation piece 10 to move. The pull rope 11 is slidably connected inside the installation groove 9. The installation groove 9 limits the installation piece 10 so that the installation piece 10 will not deviate when sliding. An elastic element 12 is sleeved on the outside of the pull rope 11. One end of the elastic element 12 is fixedly connected to the inner wall of the installation groove 9, and the other end of the elastic element 12 is fixedly connected to the installation piece 10.

[0027] When the locking block 8 needs to be pulled, the pull rope 11 is pulled, causing the mounting plate 10 to move outward. This causes the mounting plate 10 to compress the elastic element 12, causing it to deform. This allows the mounting plate 10 to pull the locking block 8 out of the slot 7, connecting block 3, and connecting block 5, thus freeing the mounting ring 2 and connecting block 3 from being restricted. At this point, the bearing housing body 1 can be maintained. Conversely, when connecting block 3 and connecting block 2 5 slide into the connecting groove 6, the pull rope 11 is released, allowing the elastic element 12 to reset. This causes the elastic element 12 to push the mounting plate 10 inward, allowing the mounting plate 10 to push the locking block 8 through the connecting block 3 and connecting block 2 5 and engage with the slot 7. This restricts the mounting ring 2 and mounting ring 4, thus completing the assembly of the bearing housing body 1 and the bearing housing.

[0028] Example 3: Based on Example 2, to achieve a more stable engagement of the locking block 8, locking grooves 14 are provided on both the upper and lower sides of the bearing housing body 1. Slots 15 are provided on the inner walls of the two locking grooves 14 on adjacent sides. Limiting rods 16 are fixedly connected inside the slots 15. A pulling block 13 is fixedly connected to the end of the pull rope 11 away from the mounting plate 10. The pulling block 13 is used to pull the pull rope 11, so that pulling the pulling block 13 can drive the two pull ropes 11 to move. The pulling block 13 is slidably connected inside the locking groove 14, which provides space for the pulling block 13 to be placed. For convenient snapping, two insert rods 17 are fixedly connected to adjacent sides of the two pull blocks 13. A limiting rod 16 passes through the insert rod 17 and is slidably connected inside the pull block 13. The insert rod 17 is slidably connected inside the slot 15. The insert rod 17 limits the pull block 13 and the slot 15, preventing them from shaking inside the snapping groove 14. A rubber block 18 is fixedly connected to the outside of the insert rod 17. The rubber block 18 has an arc-shaped structure and engages with the slot 15. When the pull block 13 is pulled, the rubber block 18 limits the insert rod 17, preventing it from detaching from the inside of the slot 15.

[0029] When the pull rope 11 needs to be pulled, by engaging the pull block 13 and pulling it upward, the pull block 13 drives the insertion rod 17 upward, causing the insertion rod 17 to pull the rubber block 18 to slide inside the slot 15. This causes the rubber block 18 to deform inside the slot 15, allowing it to detach from the slot 15. This allows the pull block 13 to pull the pull rope 11. Conversely, by sliding the pull block 13 into the engaging groove 14 and allowing the limiting rod 16 to slide through the insertion rod 17 inside the pull block 13, the rubber block 18 is compressed and deformed when it contacts the upper inner wall of the slot 15. After entering the slot 15, the rubber block 18 returns to its original position, filling the slot 15 and limiting the insertion rod 17 so that it will not detach from the slot 15 when not being pulled.

[0030] The working process of this utility model is as follows:

[0031] When maintenance is required on the bearing housing body 1, by engaging the pull block 13 and pulling it upwards, the pull block 13 moves the insertion rod 17 upwards, causing the insertion rod 17 to pull the rubber block 18 to slide inside the slot 15. This causes the rubber block 18 to deform inside the slot 15, allowing it to disengage. This, in turn, causes the pull block 13 to pull the pull rope 11, which in turn moves the mounting piece 10 outwards. This causes the mounting piece 10 to compress the elastic element 12, resulting in deformation. 10 allows the locking block 8 to disengage from the slot 7, connecting block 3, and connecting block 5, thus freeing connecting block 3 and connecting block 5 from restriction. Then, by pulling the mounting ring 2 and mounting ring 4 forward, mounting ring 2 allows connecting block 3 to disengage from the connecting groove 6, and mounting ring 4 allows connecting block 5 to disengage from the connecting groove 6, thus freeing the bearing from restriction. At this point, the bearing can be removed, and there are no other structures inside the bearing housing body 1, making it easier to maintain the bearing housing body 1.
